+	 * This is a little goofy, but the engine needs to process 1(one) entire
+	 *  tick before we actually want to start the application.
+	 * Specifically, the issue I was running into was that the editor plugin
+	 *  activates its player inputs on its very first tick, which happens *after*
+	 *  both the first level's init function and the first level's first tick.
+	 * This means that certain ui actions are being swallowed because they do not
+	 *  have the desired priority in the input handler.
+	 * I am unconvinced that this qualifies as a bug; perhaps a quirk at worst.
+	 * The fix is to just register things in the right order, which we are doing
+	 *  with this fake level that immediately passes off being the active level,
+	 *  allowing the needed 1(one) tick to pass.
